Folio of the Colentes Arcanorum

I wonder, although I have many of the 5th Ed. supplements, I havent seen any examples of these in the published works I have so far. I was planning on using a few in the net saga setting as a handy and portable way of delivering a few interesting books to the covenant which should be fairly commonly available.

Does anyone know of any examples apart from the 'fake' example in true lineages? Obviously I could invent some, but it would be nice to use some from the official bckground.

Lough Caillte has 2 folio in their library. Not published canon, but they're there.
